‘Rarest white diamond ever’ to be sold in London

A flawless diamond, the size of a large strawberry, is expected to fetch a world record price when it comes to market at Sotheby’s in London this month.Weighing just over 102 carats, the round, brilliant white stone is smaller than a 118-carat oval diamond sold in Hong Kong in 2013, which currently holds the record price per carat.
